Molecular fingerprinting with femtosecond lasers
Julien Mandon, Guy Guelachvili, Nathalie Picqué
Molecular fingerprinting through absorption spectroscopy is a powerful analytical method. Wide spectral ranges are explored with Doppler-limited resolution. Fast data acquisition,…
Concentration-modulation FT emission spectroscopy of TiCl_4/He plasma. Analysis of the C ^4Δ- X ^4 ΦΔv=0 perturbed transitions of TiCl
Hervé Herbin, Robert Farrenq, Guy Guelachvili +1
A TiCl_4/He plasma is observed by high resolution double-modulation FTS using concentration-modulation as a selective detection method. Analysis of the C ^4Δ- X ^4 ΦΔv=0 transition…
Frequency modulation Fourier transform spectroscopy
Julien Mandon, Guy Guelachvili, Nathalie Picqué
A new method, FM-FTS, combining Frequency Modulation heterodyne laser spectroscopy and Fourier Transform Spectroscopy is presented. It provides simultaneous sensitive measurement o…
Spatial variation of the laser fields and electron dynamics at a gas-solid interface
Georges Raseev, Eric Charron
In the long wavelength domain, typically for wavelengths lambda > 100 angstroms, the laser fields are usually taken as independent of the spatial coordinate. However, at the gas-so…
